Given:
μ = 2 min, population mean
σ = 0.5 min, population standard deviation
We want to find P(x>3).
Calculate the z-score
z= (x-μ)/σ = (3-2)/0.5 = 2
From standard tables, obtain
P(x ≤ 3) = P(z ≤ 2) = 0.9772
Therefore
P(x > 3) = P(z > 2) = 1 - 0.9772 = 0.0228
Answer: 0.02275
When we <em>divide </em>both sides of the <em>inequality</em>,
3x > 27 by 3, <em>3x(3) > 27(3)</em>
we get x > 9, as the <em>simplified form </em>of the<em> inequality.</em>
Thus, giving us the answer of:
<em>x > 9</em>

Answer:
Zero(0)
Step-by-step explanation:
From the given information, we are to determine the probability that both ships are hit given that the pirate shoots first.
There are two scenarios
Since the pirate is to shoot first
- If the pirate misses, the Captain's ship is not hit. Therefore there's no chance of both ships getting hit.
- If the pirate hits, we are told that if his ship has been hit, Captain Daniel will always miss. Therefore there is also no chance of both ships getting hit.
P(both ships to be hit given that pirate shoots first) =0
